Health risks

Thrombosis
Thrombosis is a condition in which a blood clot (thrombus) forms in a blood vessel. This can lead to a deep vein thrombosis or a pulmonary embolism, which can have serious health consequences. The risk of thrombosis increases during long journeys, especially when sitting still for extended periods in an airplane, car, or bus.
How do you get thrombosis while travelling?
During long journeys, you often move very little. As a result, blood flows more slowly through the veins, especially in the legs. This increases the risk of a blood clot. This risk is higher in cases of:
- Travelling longer than 4 hours
- Little exercise or sitting still
- Being overweight
- Pregnancy
Use of the contraceptive pill or hormone therapy
Previous thrombosis or pulmonary embolism
- Certain medical conditions such as cancer or heart failure
What are the symptoms?
During or after your trip, watch out for the following symptoms:Pain, swelling, or redness in a leg (usually in the calf)
Tightness or pain in the chest
Sudden shortness of breath
How can you prevent thrombosis?
You can reduce the risk of thrombosis while travelling by:- Exercising regularly: walk around every hour or do leg exercises
Drinking plenty of water (no alcohol or caffeine)
Wearing loose-fitting clothing
